Abstract
Four new monoterpenoids, including two new acyclic monoterpenoids (2R, 6R)-2, 6-dimethyl-8-isovaleroxyoctan-1-ol (1) and (2S, 6S)-2, 6-dimethyl-8-isovaleroxyoctan-1-ol (2), as well as two new iridoids stenopterins F-G (3 and 4), together with fifteen known compounds (5–19), were isolated from whole dried material of Valeriana stenoptera. Stenopterin F was the first reported iridoids with n-butoxyl in the Valerianaceae family. The structures of new compounds were established on the basis of extensive spectroscopic analysis.
